AUTONOMIC NERVOUS SYSTEM​AND VASCULAR ASSESSMENTS

LD-OXY Model D001

1 - To analyze the pulse waveform (Photoelectrical plethysmography or PTG) provided by the oximeter. ​​​​

2 - To analyze the basic rhythms of the NN or RR intervals in heart rate. Both in the time domain and in the frequency domain.

The PTG analyses the peripheral circulation and detection of the beat to beat heart rate.PTG uses transmitted infrared and red light to measure oxygen saturation and relative blood volume in the fingertip. PTG waveform are reflective of blood movement in cutaneous vessels and can be used to identify synchronous depolarization of cardiovascular tissue.​
